Description

    CROSS-REFERENCE
  • This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/982,002, filed on Apr. 21, 2014, which is incorporated herein by reference in its entirety.
  • BACKGROUND
  • The present disclosure relates to systems, devices, and methods for managing health and disease with portable electronic devices. In particular, the present disclosure relates to systems, devices, and methods for managing cardiac health with mobile computing and/or telecommunications devices.
  • The use of smartphones, tablet computers, wearable computers, smartwatches and “smart” accessories is becoming increasingly prevalent. Smartphones are almost ubiquitous in high income countries and are increasingly popular in middle and low income countries as the costs of production decrease and Internet access becomes more available. This increased prevalence of computing power and devices offers many opportunities for improved ways of monitoring health and placing health management more in the control of the end-user or patient rather than medical professionals who may be relatively inaccessible.
  • Applications have been provided for smartphones, tablet computers, wearable monitoring devices, and the like to provide the user with the ability to track various parameters for health. The user may be able to enter into the application(s) his or her weight and diet, for example. An on-board accelerometer of the device may track the sleep and/or activity levels of the user. Heart rate may be monitored using the on-board camera and flash of the device and some devices even include on-board electrodes for monitoring heart rate. Accessories for these devices have been available to track activity levels and other health parameters as well.
  • Cardiovascular disease is a leading cause of death in the world and is prevalent in the populations of high-income and low-income countries alike. Heart rate measurement, blood pressure measurement, and electrocardiography are widely used techniques for diagnosing the cardiovascular health of patient. While device to measure heart rate and blood pressure are highly prevalent and accessible, many of these devices can be less than ideal in at least some cases. For example, such devices may provide only the heart rate and blood pressure of a patient but fail to provide many other important diagnostic parameters which can be determined or derived from heart rate and blood pressure. Also, these devices may not be portable and it may be difficult to make continuous measurements which can provide important health and diagnostic information. Electrocardiography may not be accessible to users as would be ideal as access to professional clinics is often still required.
  • SUMMARY
  • Recognized herein is a need for improved health monitoring systems, devices, and methods to address one or more of these challenges and which may take advantage of the increased prevalence of computing power and telecommunications. This increased prevalence may offer opportunities for improved ways of monitoring health and placing health management more in the control of the end-user or patient rather than medical professionals who may be relatively inaccessible.
  • The present disclosure relates to systems, devices, and methods for managing health and disease with portable electronic devices. In particular, the present disclosure relates to systems, devices, and methods for managing cardiac health with mobile computing and/or telecommunications devices.
  • Aspects of the present disclosure provide systems, devices, and methods for health monitoring. Such systems, devices, and methods may take advantage of the increased prevalence of computing power and telecommunications and provide accessible ways for a user to monitor his or her health. Many smartphones, tablet computers, wearable monitoring devices, and the like available or soon to be available in the market may have the ability to interface with a wearable accessory component such as a “smartwatch.” The smartwatch or secondary computing device may include a display and a user interface through which the user can interact with the primary computing device. In some embodiments, the wearable component or device may be a wearable monitoring device or wearable monitoring device, terminal or display (e.g., in communication with data over a network, such as a cloud network, a cellular network or any other network). In some embodiments, the wearable component or device may provide at least a portion of functions provided by smartphones, tablet computers, wearable monitoring devices, and the like. Any aspects of the disclosure described in relation to secondary devices may equally apply to primary devices (e.g., wearable monitoring devices) at least in some configurations, and vice versa.
  • In many aspects, systems, devices, and methods are provided such that the smartwatch or secondary computing device can provide additional health monitoring features. For example, heart rate (HR) and/or an electrocardiogram (ECG) may be taken with such smartwatch or secondary computing device associated devices. The straps of a smartwatch may be interchangeable and embodiments of the present disclosure may provide a smartwatch strap having a health monitoring function. The strap may comprise one or more electrodes configured to contact the skin of the user to continuously or on contact measure the heart rate or electrocardiogram of a user. The strap may also comprise an output to communicate the measured parameter to the smartwatch or primary computing device (e.g., the smartphone, the tablet computer, etc.) The output may comprise a WiFi transmitter, a Bluetooth transmitter, an audio or ultrasound acoustic transmitter or speaker (e.g., as described in U.S. Pat.

An attachable monitoring device may comprise one or more of one or more sensors 36 and 37, a processor 39, a computer readable media 38, a receiver 40, and a transmitter 41. Sensors 36 and 37 are configured to sense biometric parameter data from a user, and to transmit the data to a processor 39. A processor 39 may be configured to process data received from various sensors. For example, in an embodiment, sensors 36 and 37 comprise electrodes that record electric potentials. In the same embodiment, the electric potentials transmitted from sensors 36 and 37 may be transmitted to processor 39 which transforms the sensed data into an electrocardiogram. In an embodiment, processor 39 may further analyze data received from sensors 36 and 37, for example, by comparing the received data to normal data values. In an embodiment, a processor 39 is configured to analyze an electrocardiogram recorded by sensors 36 and 37. For example, a processor 39 may analyze an electrocardiogram recorded from a user for arrhythmias, heart rate variability, or heart rate turbulence. A processor 39 is functionally coupled to a computer readable media 38 which comprises software which comprises executable commands that may be executed by processor 39. For example, software stored on a computer readable media 38 may cause processor 39 to analyze an electrocardiogram. Software stored on a computer readable media 38 may cause a processor to encode biometric parameter data for transmission. Processor 39 is coupled to receiver 40 which is configured to receive a wireless transmission from a computing device. In an embodiment, receiver 40 transmits a received wireless transmission to the processor 39. In the same embodiment, a received wireless transmission comprises an executable command that causes processor 39 to perform some function. For example, a received wireless transmission may cause a processor 39 to activate one or more sensors causing the one or more sensors to sense a biometric parameter from a user. For example, a received wireless transmission may cause a processor 39 to transmit a signal to transmitter 41. A wireless transmitter 41 is coupled to processor 39. In an embodiment, a wireless transmitter 41 is configured to transmit a wireless signal to a computing device. For example, in an embodiment, a transmitter transmits an electrocardiogram recorded with the wearable measuring device to a computing device with a screen display, causing the screen display of the computing device to display the electrocardiogram. In an embodiment, an attachable monitoring device comprises a watchband which comprises a body comprising one or more straps which comprise one or more of sensors 36 and 37, processor 39, computer readable media 38, receiver 40, and transmitter 41. In the same embodiment, a wireless signal is received by receiver 40 from a mobile computing device comprising an executable command that may be carried out by processor 39. In the same embodiment, the executable command causes processor 39 to cause sensors 36 and 37 to sense a biometric parameter of a user and cause transmitter 41 to transmit the biometric parameter sensed by sensors 36 and 37 to a computing device. In an embodiment, a computing device transmits an executable command to an attachable monitoring device in response to biometric parameter data of a user. For example, a computing device comprising, for example, a smartphone may receive biometric parameter data of a user from a sensor that is engaged with the user, wherein the biometric parameter data comprises a heart rate. In an embodiment, the smartphone will analyze the received heart rate and make a determination if there is a need to, for example, record an electrocardiogram of the user. When the smartphone determines that there is a need to record an electrocardiogram of the user based on the heart rate data, it will transmit a signal to an attachable monitoring device that, for example, comprises a watchband causing the watchband to record an electrocardiogram. The watchband may transmit the electrocardiogram to the smartphone for display on the smartphone. In an embodiment, the watchband is couple to a smartwatch housing, and transmits the electrocardiogram to the smartwatch for display on the smartwatch screen.
  • In an embodiment, the attachable monitoring device is in communication with a portable computing device. The portable computing device may comprise a wearable monitoring device, a smartphone, a tablet computer, a laptop computer, or the like. The portable computing device may be in communication with the attachable monitoring device through a wired (e.g., Lightning, USB, FireWire, or the like) or a wireless connection (e.g., WiFi, cellular, Bluetooth classic, Bluetooth low energy, NFC, ultrasound communication, or the like) through the wireless transmitter and/or speaker and microphone of the attachable monitoring device. The portable computing device may provide a variety of computing and application functions while the attachable monitoring device may provide a subset of such functions in a more convenient manner (e.g., notifications, time, date, weather, alerts, device control, etc.). An application may be provided for smartphones, tablet computers, wearable monitoring devices, and the like to provide the user with the ability to track various parameters for health. The user may be able to enter into the application(s) his or her weight and diet, for example. In another example, an on-board accelerometer of the device may track the sleep and/or activity levels of the user. Heart rate may be monitored using the on-board camera and flash of the device. In some embodiments, the devices may include on-board electrodes for monitoring heart rate. Accessories for these devices may be used to track activity levels and other health parameters as well.
  • In an embodiment, an attachable monitoring device may comprise an accelerometer which may be used to detect the activity level and patterns of the user. The attachable monitoring device may be in continuous contact with the user throughout an extended period (e.g., an hour, a half-day, a day, or more) and various physiological parameters may be continuously measured. For example, physiological parameters such as activity level, heart rate, hydration, ECG, etc. may be continuously measured and correlated with one or more of each other. For example, correlating the activity level of the user with the heart rate of the user may provide an indication as to the fitness level of the user. Significant increases in heart rate with trivial activity and/or slow decrease in heart rate after trivial activity may indicate to the user that he or she has a low fitness level and low cardiovascular health. Conversely, insignificant increases in heart rate with substantial activity and/or a healthy decrease in heart rate after significant activity may indicate to the user that he or she has a healthy or high fitness level and a healthy or high cardiovascular health. ECG may also be correlated with activity level to detect any cardiac abnormalities such as arrhythmias that occurs during physical activity. For example, the user may be prompted or notified to take an ECG immediately after a high level of user physical activity as indicated by heart rate, skin hydration, and/or the accelerometer.
